另外,当非晶矽取代复晶矽薄膜后,由于非晶矽比起复晶矽有较小的晶粒边 界密度 ( grain boundary density )及较少的扩散管线(diffusion pipeline),因此可得到具有较佳热稳定性的二矽化钴。

The growth velocity for recrystallized grain is proportional to the driving force of recrystallization, which is determined by the grain boundary energy and dislocation density.
再结晶晶粒的生长速度与再结晶驱动力成正比,再结晶驱动力取决于晶界能和位错密度。
Results show that the contents of intergranular oxygen and total grain boundary phase as well as the density of sintered samples have maximum values with increasing the holding time.
研究发现,由于晶界相中的氧含量随保温时间的延长先增加然后明显降低,导致烧结体中晶界相的总量和致密化程度随保温时间的增加有一最大值。
